I was using Two Little Fishes phosban whatever stuff, it's too fine of a material for my taste. So I switched to BRS's GFO and I am very pleased with it. It comes in larger containers and it's cheaper.

This product really performs when used in a reactor and will last at least a month in my 91 gallon system. My phosphates are no longer a worry for this reefer!

.i watched a few of your videos and review videos from your customers. i had a lot of problems with my phosphate and this product would help with it.so there was nothing to loss this would have been my last draw. i ordered the BRS GFO Reactor, as well with the GFO. When i started to use this product with in 24 hours my phosphate was zero....i have worked for years trying to get this down to zero i have used different things over the years and nothing works better then this stuff.THANK YOU THANK YOU THANK YOU.i have never had a problem since.My phosphate still sits at zero.

I placed GFO in both my reactors on my two salt water tanks. One fish only the other a 20 gallon long reef tank. My phosphates went down to 0 ppm. Never had that happen till now.Highly recommended for any reefer.
